NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Feb. 27, 1906 Application led August 9,1905. Serial No. 273,464.

To all whom, t may con/067%.

Be it known that T, JOHN M. KILDUFF, a citizen of the United States, residing at the city of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improved Non-Refillable Bottle, of which the following is a specification.

The object of this invention is to adapt bottles and such like so as to `prevent their being refilled after having been once emptied of their contents.

The invention particularly relates to an improvement on and which is applicable to the features of a prior invention by me for a sirnilarobject embraced in an application for Letters Patent of the United States filed May 1o, 1905, Serial No. 259,821.

The improvement consists in the application to and combination with the contrivances of said prior invention of a coiled or spiral spring for the purpose of holding the valve closed under certain contingencies while otherwise leaving it free to operate, all substantially as hereinafter described.

Tn the drawings forming part of this speciiication, Figure l is a central vertical section of the neck and a portion, broken off, of the body of the bottle next adjacent thereto. Fig. 2 is a horizontal cross-section, line 2 2, Fig. 1. Figs. 3 and 4 are vertical sectional views illustrating modifications, as will hereinafter appear.

In the drawings, Ais the body, shown only in part and broken off, and B is the neck of a bottle, which maybe of any desiredform, size, or design.

O is a valve-seat in the neck B and at or near its junction with the body A. D is a valve to seat on said seat O. The valve D is shown as more or less of a round or ball shape. It may, however, be of any other desired or proper shape, as also its seat; but they must be adapted to each other and for the opening D3 of the valve-seat to be open for the outward flow or passage therethrough of the contents of the bottle when the valve is off its seat and for said opening to be closed to such flow or passage when the valve is on its seat, as also to then prevent the flow or passage of liquid or anything else through said opening into the bottle-body A.

D2 is a central stem of the valve. This valve-stem extends upwardly into the neck B, and its axis is coincident with the central vertical axis of the neck, valve, and valveseat.

E is a vertical cage secured by cement or any other suitable means or in any other suitable manner, and at its inner or lower end portion E2 within and to the inner side of the bottle-neck and in a position just above and beyond the valve-seat O and its valve D both when the valve is on and ofi its seat. The inner or lower end portion E2 and the upper or outer end portion E3 of the cage E are closed, as shown and as will hereinafter more fully appear.

F is a fixed vertical tube axially coincident with the bottle-neck. This tube F extends from the lower end to nearly the upper end E1 of the cage E, and it is open at both ends, and its upper end is in communication with a space or chamber h about and between the tube and the inner side of the upper end portion E3 and upper end E4 of the cage E. As shown, the tube F is secured to and within a plug G, of cork or other suitable material, whichiills and closes the lower end portion E2 of the cage between its inner side and the outer side of tube F. The external diameter of the upper and unsecured end portion E3 of the cage is somewhat less than the internal diameter of the bottleneck, leaving a space a entirely about and between said end portion and the bottle-neck and which is in open communication with the chamber B2 of the bottle-neck above the cage E.

b b are lateral ports or openings, which may be more or less in number, through the side of the upper end portion E3 of the cage and making communication between the -open space a thereabout and the space h,

which lies between the outer side of the tube F and the inner side of the cage E.

H, Figs. 1 and 2, is a stationary central tube within the tube F and extending downward from the upper end E4 toward the lower end portion E2 of the cage, and d is an open space entirely about and between the central tube H and the inner side of the surrounding tube F. The valve-stem D2 of the valve enters into the central tube H, which serves as a guide to the stem and its valve in their upand-down movement relative to the valveseat.

f is a coiled or spiral spring in central tube l H and confined end to end between the upper closed end of the tube and the upper end of the valve-stem.

From the above description it is plain that the contents of the bottle can be emptied and discharged when the cork or stopper K is re- IOO moved at the then open end of the bottleneck by properly upsetting the bottle for the reason that the valve will then move from its seat sufficiently therefor, and again that the bottle cannot be refilled, as under all contingencies or circumstances, except as hereinafter stated, the valve of itself and independent of the action of its spring f will close and remain closed and so prevent it, while in attempting to refill the bottle by submerging it in liquid and there maintaining it in a substantially horizontal position said spring acting on the valve (the spring having sufIicient tension therefor) will close the valve and hold it closed against the passage of any liquid through the opening of the valve-seat into the bottle.

In lieu of the valve-stem being arranged as has been described for movement within the central tube II the valve-stein, F ig. 3, may be tubular and arranged to move on a fixed central vertical guide-stem g of the cage E in substitution for said tube. In this case the spring f is housed within the then tubular valve-stein and is confined end to end between the lower closed end of the tubular stem and the lower end of the guide-stem, and this particular arrangement may also be carried out as is shown in Fig. 4, which, as is evident, varies from the arrangement Fig. 3 only in slight and unimportant ways.

It is to be observed that it is impossible to reach either the valve or the springf with a wire or other implement inserted at the open end of the bottle-neck.

The several parts herein described other than those particularly spoken of can be made of porcelain is not to be tions.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

A bottle, or such like, having a valve-seat in its neck, a valve to seat on said seat and having an upward-projecting guiding-stem, a cage secured within and to the neck above said valve and its seat and having upper and -lower closed ends and an open space around,

and also having lateral or side ports in its upper end portion, and a vertical tube within the cage, open at its upper and lower ends and held by the lower end portion and its upper end portion opposite to said ports of the cage, and having an open space about and between it and the inner side of said upper end portion of the cage, in combination with a spiral or coiled spring adapted and arranged to act on said valve, and a tube surrounding and confining said spring, substantially as described, and for the several purposes speciiied.

In witness whereof I have hereunto set my hand in the presence of two subscribing wit- IleSSG/S.
